I have taken a different approach to the surface propulsion problem with my little sub project.
My initial design was to couple the sub with a surface craft like a small pontoon section which would carry a compressor, generator, and outboard motor to power the sub. Now I am adding a motor mount on the back of the sub that can accept a small outboard like maybe 20 horsepower for surface travel. When I get to the dive site, the small outboard will be removed and stored on an accompanying motor boat while the sub goes down, or possibly inside the sub. I have a sketch of the structure for the rear ballast tank and motor mount on frappr. Here's the link to see what it looks like.

I've got the parts for this in the shop and will start fabrication as soon as I finish the hatch hinges and lock-down dogs. Hope to get some pictures of that part up soon. ( Man!!! it takes a lot of grinding to fab these parts)

Hello Frank,
I would not use an outboard on a smal l p-sub as cavitation plate needs to be quiet - condition you will not have on your sub - for the prototype i tested a combination of electric motor in the sub and a generator at the raft - this works well.
